An air handling device () includes an air flow path () in which a charge section () for charging dust in an air to be handled, and a precipitator () for collecting the charged dust are placed. The charge section () includes a discharge electrode () and a counter electrode () to perform diffusion charging. A diffusion space () is provided at a location between the charge section () and the precipitator ().

Air handling device

The present invention relates to a charging device having a charge section () for charging a floating particle in an air to be handled, and an air handling device (an air cleaning device) having the charging device. The charge section () is constituted by a first charge section () adopting an impact charging technique and a second charge section () adopting a diffusion charging technique. With this structure, charging and collection of dust can be accomplished only in the casing of the device, and therefore, an increase in size of the device can be avoided.

Charging device, air handling device, method for charging, and method for handling air

A dust collector includes a charging part () for charging dust with electricity and a dust collecting part (). Each of a dust collecting electrode () and a high-voltage electrode () that constitute the dust collecting part () includes: a base () with a rectangular grid structure having a large number of vent holes () formed therein; and projections () extending into the vent holes () of the opposed electrode (). The dust collector collects dust by generating an electric field between the dust collecting electrode () and the high-voltage electrode ().

Dust collector

In a discharge device for performing streamer discharge between a discharge electrode () including a plurality of discharge parts () and a counter electrode () including a plurality of counter parts () confronting the discharge parts (), a resistor () is provided in a current carrying path between power source means () and the discharge parts ().

Discharge device and air purifier

A discharge unit () and a heat exchanger () are disposed in an air passageway (). In the discharge unit (), a rod-like discharge electrode () and a plate-like counter electrode () are disposed perpendicular to the flow of air, and lie along the heat exchanger (). Upon application of voltage to both the electrodes (), streamer discharge is performed between the electrodes (), whereby an active species capable of decomposition of a component to be processed is produced.
